Cut with a Tube Cutter — Cut the Copper Pipe
Part of project
How to Install a Water Hammer Arrestor to Stop Banging Pipes · Step 3 of 7
In this video
The final method shown is using a standard metal tube cutter, often used for copper pipes. The narrator suggests this as an 'in a pinch' method. The cutter is clamped onto the pipe, and the user rotates it around the pipe, tightening the knob slightly with each rotation until the cutting wheel cuts through. This method works on smaller diameter PVC but is slow. It does, however, produce a clean, square cut.
Goal: Cut small-diameter PVC pipe when no other specialized tools are available.
- This is a good method to use 'in a pinch' if you already own a tube cutter for metal pipes.
- This method is much slower than other options and is limited to smaller pipe diameters.

FAQs
Do I really need all the listed tools for this water hammer arrestor installation, or can I manage with fewer?
For a successful and leak-free installation, the tubing cutter, deburring tool, and adjustable wrenches are essential. While you might try a hacksaw, a tubing cutter ensures a cleaner, square cut vital for compression fittings. The deburring tool prevents damage to the O-ring and ensures a tight seal, so these are not optional for a reliable outcome.
What are the critical safety precautions I must take when installing a water hammer arrestor, especially as a beginner working with plumbing?
Always begin by shutting off the main water supply to your home and draining the lines to prevent unexpected floods or sprays. Wear safety glasses to protect against debris and gloves to prevent cuts from sharp pipe edges. Double-check that the water is completely off before making any cuts to the pipe.
How much time should a beginner budget for this water hammer arrestor installation, and what's the approximate material cost?
A beginner should typically budget 1 to 2 hours for this project, allowing time for preparation, precise cutting, assembly, and thorough leak checks. The primary material cost will be for the water hammer arrestor itself and the compression tee, generally ranging from $30-$60 depending on your specific chosen parts and local pricing.
What are the most common mistakes beginners make when installing a water hammer arrestor, and how can I avoid them?
A frequent mistake is not deburring the pipe ends thoroughly, which can lead to leaks at the compression fitting due to an improper seal. Another common error is under-tightening the compression nuts; ensure they are snug and firm, but avoid overtightening and stripping the threads. Also, remember to use Teflon tape on the arrestor's threaded connection points, but not on the compression connections themselves.
